SYSTEM CONSISTING OF A FUEL CELL AND OF A HEAT EXCHANGER

摘要

The invention relates to a system consisting of a fuel cell and of a heat exchanger, whereby the heat exchanger is flow-coupled to the fuel cell in such a manner that a gaseous reactant for the fuel cell is preheated in the heat exchanger that is flow-connected upstream in relation to the fuel cell. In addition, at least a portion of the waste gas from the fuel cell is guided through the heat exchanger connected downstream in relation thereto. The aim of the invention is to simplify the entire system, to reduce the installation space and weight, and to improve its functioning. To these ends, the invention provides that the heat exchanger is placed directly against the fuel cell and is integrated therewith whereby resulting in the provision of a direct flow transfer from the heat exchanger to the fuel cell.
